METAL CONTAINER.

Application filed November 7, 1923. Serial No. 673,279.

reference being had to the accompanying drawing and to the figures ofreference marked thereon. 4

The invention relates to new and useful improvementsin metal containers,and more particularly toa metal container wherein one end ishermetically secured to the body portion of the container by a sealingmember that can be easily removed- An object of the invention is toprovide. a

container of the above type wherein an integral sealing member holds theremovable end in close sealed contact with the container body, andwherein said sealing member includes a depending flange formed withslits extending from the lower edge thereof upwardly into the flan e,thus forming readily bendable sections ying side by side which may beturned underneath an external. bead on the container body for drawingand holding the cover on the con-- tainer body in tight sealed contacttherewith, and which may be readily bent without the use of specialtools for releasing the ring from the container.v

A further object of the invention is to provide a container of the abovetype havmg a contracted neck portion adjacentits upper end so that theextreme diameter of the detachably closed end is substantially .the sameas t e maximum diameter of the body of the container, and the lower endsof the bent portions of the sealing ring are housed in the space formedby the contracted portion.

. These and other objects will in part be obvious and will in part behereinafter more 4 fully disclosed.

' Inthe drawin Figurel is a view partly in side elevation and partly intransverse section showing a container embodying our improvements; tionof a portion of the container with the sealing ring secured thereto;

Fig. 3 is a sectional view of a portion of thecontainer showing theclosing end and Fig. 2 is an enlarged view in side eleva-' the sealingring as well as the upper portion of the container body, and a Fig. 4 isa view similar to Fig. 2, but showing the bendable portions of thedepending flange turned up for the purpose of releasing the sealing ringfrom the container bod j The container is preferably of a cylindricaltype. One end of the container is secured thereto in the ordinary way bydouble-seaming and it has t been thought necessary to illustrate iii 6h?drawings, this end of the container. The other end of the container bodyis closed by a cover or end,

and a sealing ring which hermetically secures theend to the containerbody. The sealed end is preferably put on by the manu facturer of thecontainer, after which the contents are placed therein by the packer andthe other end attached by the ordinary double-seaming.- This end whichhas the sealing ring attached thereto is provided with an outwardly anddownwardly rolled flange. The container body is contracted beneath therolled flange so as to form a housing for the lower end of the flange ofthe sealing ring. The cover or end has a dependin flange fitting withinthe container body, and a laterally projecting por tion which overliesthe rolled flange on the container body. The sealing ring overlies theprojecting portion of the end and extends a slight distance inwardlytoward the center of the can end. It also extends downwardly around therolled flange to a point well underneath the same when the sealing ringis attached to the container body. Said depending flange is formed withslits extending from the lower edge thereof upwardly to a point oppositethe maximum diameter of the rolled flange. These slits form bendableportions which may be raised so as to release the sealing ring from thecontainer body.

Referring more in detail to the drawings, we have shown our improvedcontainer as non consisting of a cylindrical container body 1 having arolled flange 2 at one end thereof. This flange is rolled outwardly anddownwardly and inwardly and its free edge 3 is slightly spaced from thewall of the container. The container is contracted at 4 so that theouter edge of'the rolled flange is substantially over the wall of thebody portion of the con- .contents thereof.

tainer. The wall of the container is, however, free from shoulders thatwould in any way prevent the ready emptying of the by a cover or can end5. Saidcan end5 includes a section 6 which extends across the mouth ofthe container body toa point 7 well over the rolled flange 2. Said endis then bent inwardly and thence downwardly as at 8. This downwardlyprojecting portion conforms generally to the inner surface of thecontainer body and is adaptedto frictionally engage the same. The end isheld on the container body by a sealing ring 9. Said sealing ring 1sprovided with a portion which overlies this laterally projecting part ofthe I can end which in turn overlies the rolled flange 2, and extendsinwardly to a point 10 which is well inside of the vertical wall of thecontainer body. The end is preferably recessed to provide a pocket toreceive the inner edge 10 of the sealing ring and this inner edge ispreferably bent back so as to conceal the raw edge of the metal asclearly edges of the slit will come together,

' of. It will readily neck portion shown in Fig. 3 of the drawings. Thesealing ring has a depending flange 11. Said depending flange at itsextreme lower end is turned upwardly as at 12 so as to conceal the rawedge of the metal and strengthen said lower edge of the flange. Saidflange is provided with parallel slits 13, 13 which are comparativelyclose spaced, and these slits extendfrom the bottom edge of the flangeto.

a point opposite the maximum diameter of the rolled flange 2 when thesealing ring is secured to the container. These slits are so formed thatwhen the flange is turned underneath the rolled flange 2 of the canbody, Itlhe t us making a continuous sealing contact between the lowerportion of the flange and the rolled bead on the container body. Y Asclearly shown in Fig. 3, these bendable strips 14 formed by the slits 13are adapted to be bent underneath the rolled bead or flange of thecontainer body, and to a point which permits the rolled flange to beslightly reduced during the placing of the sealing ring on the containerbody, and thus a very resilient seal is produced wherein the expansionof the metal tends to draw the parts into tighter engagement, with thesealing material placed between the overlying portion of the can end andthe rolled flange of the can body. The extreme lower portions of thestrips 14 are bent outwardly at 15 so as to lie at an angle to the wallof the body portion of the container. The contracting of the body of thecontainer the lower ends of these forms a housing for access to be hadto strips. and also enables the strip for prying out the lower endtherebe seen that if the strips are bent outwardly as shown in Fig. 4:,they will release their hold on the rolled flange The container body isclosed 1 up to the point of the maximum diameter of the flange, and thusthe sealing ring can be readily lifted from the container body.

It will be noted from the above that there has been provided a sealingring which forcibly holds the end in engagement with the container bodythroughout its entire circumference. The sealing ring can be releasedfrom the container body without the use of any special tools, and whenreleased, it can be removed and will leave the container with a frictiontop closure.

It will be further noted that when these projecting strips are bentupwardl to release the' ring from the container bo y, there is norupturing of the metal and therefore, said strips may be readily raisedto their releasing position.

Then again, it will be noted that when desired, the sealing ring may bereplaced on the end of the container body and the bendable strips bentunderneath the flange by hand, so that the end will be firmly held onthe container body and in a measure, the package re-sealed by thebending under of these portions.

It is obvious that minor changes in the details of construction may bemade without departing from the spirit of the invention as set forth inthe appended claims.
